Description of Related Art

Computing devices are known to communicate data, process data, and/or store data. Such computing devices range from wireless smart phones, laptops, tablets, personal computers (PC), work stations, and video game devices, to data centers that support millions of web searches, stock trades, or on-line purchases every day. In general, a computing device includes a central processing unit (CPU), a memory system, user input/output interfaces, peripheral device interfaces, and an interconnecting bus structure.

As is further known, a computer may effectively extend its CPU by using “cloud computing” to perform one or more computing functions (e.g., a service, an application, an algorithm, an arithmetic logic function, etc.) on behalf of the computer. Further, for large services, applications, and/or functions, cloud computing may be performed by multiple cloud computing resources in a distributed manner to improve the response time for completion of the service, application, and/or function.

Of the many applications a computer can perform, a database system is one of the largest and most complex applications. In general, a database system stores a large amount of data in a particular way for subsequent processing. In some situations, the hardware of the computer is a limiting factor regarding the speed at which a database system can process a particular function. In some other instances, the way in which the data is stored is a limiting factor regarding the speed of execution. In yet some other instances, restricted co-process options are a limiting factor regarding the speed of execution.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 is a schematic block diagram of an embodiment of a large-scale data processing network that includes data gathering device 1, data gathering devices 1-1 through 1-n, data system 2, data systems 2-1 through 2-N, data 3, data 3-1 through 3-n, a network 4, and a database system 10. The data systems 2-1 through 2-N provide, via the network 4, data and queries 5-1 through 5-N data to the database system 10. Alternatively, or in addition to, the data system 2 provides further data and queries directly to the database system 10. In response to the data and queries, the database system 10 issues, via the network 4, responses 6-1 through 6-N to the data systems 2-1 through 2-N. Alternatively, or in addition to, the database system 10 provides further responses directly to the data system 2. The data gathering devices 1, 1-1 through 1-n may be implemented utilizing sensors, monitors, handheld computing devices, etc. and/or a plurality of storage devices including hard drives, cloud storage, etc. The data gathering devices 1-1 through 1-n may provide real-time data to the data system 2-1 and/or any other data system and the data 3-1 through 3-n may provide stored data to the data system 2-N and/or any other data system.

FIG. 1A is a schematic block diagram of an embodiment of a database system 10 that includes data processing 7 and system administration 8. The data processing 7 includes a parallelized data input sub-system 11, a parallelized data store, retrieve, and/or process sub-system 12, a parallelized query and response sub-system 13, and system communication resources 14. The system administration 8 includes an administrative sub-system 15 and a configuration sub-system 16. The system communication resources 14 include one or more of wide area network (WAN) connections, local area network (LAN) connections, wireless connections, wireline connections, etc. to couple the sub-systems 11, 12, 13, 15, and 16 together. Each of the sub-systems 11, 12, 13, 15, and 16 include a plurality of computing devices; an example of which is discussed with reference to one or more of FIGS. 7-9 .

In an example of operation, the parallelized data input sub-system 11 receives tables of data from a data source. For example, a data set no. 1 is received when the data source includes one or more computers. As another example, the data source is a plurality of machines. As yet another example, the data source is a plurality of data mining algorithms operating on one or more computers. The data source organizes its data into a table that includes rows and columns. The columns represent fields of data for the rows. Each row corresponds to a record of data. For example, a table include payroll information for a company's employees. Each row is an employee's payroll record. The columns include data fields for employee name, address, department, annual salary, tax deduction information, direct deposit information, etc.

The parallelized data input sub-system 11 processes a table to determine how to store it. For example, the parallelized data input sub-system 11 divides the data into a plurality of data partitions. For each data partition, the parallelized data input sub-system 11 determines a number of data segments based on a desired encoding scheme. As a specific example, when a 4 of 5 encoding scheme is used (meaning any 4 of 5 encoded data elements can be used to recover the data), the parallelized data input sub-system 11 divides a data partition into 5 segments. The parallelized data input sub-system 11 then divides a data segment into data slabs. Using one or more of the columns as a key, or keys, the parallelized data input sub-system 11 sorts the data slabs. The sorted data slabs are sent, via the system communication resources 14, to the parallelized data store, retrieve, and/or process sub-system 12 for storage.

The parallelized query and response sub-system 13 receives queries regarding tables and processes the queries prior to sending them to the parallelized data store, retrieve, and/or process sub-system 12 for processing. For example, the parallelized query and response sub-system 13 receives a specific query no. 1 regarding the data set no. 1 (e.g., a specific table). The query is in a standard query format such as Open Database Connectivity (ODBC), Java Database Connectivity (JDBC), and/or SPARK. The query is assigned to a node within the sub-system 13 for subsequent processing. The assigned node identifies the relevant table, determines where and how it is stored, and determines available nodes within the parallelized data store, retrieve, and/or process sub-system 12 for processing the query.

In addition, the assigned node parses the query to create an abstract syntax tree. As a specific example, the assigned node converts an SQL (Standard Query Language) statement into a database instruction set. The assigned node then validates the abstract syntax tree. If not valid, the assigned node generates a SQL exception, determines an appropriate correction, and repeats. When the abstract syntax tree is validated, the assigned node then creates an annotated abstract syntax tree. The annotated abstract syntax tree includes the verified abstract syntax tree plus annotations regarding column names, data type(s), data aggregation or not, correlation or not, sub-query or not, and so on.

The assigned node then creates an initial query plan from the annotated abstract syntax tree. The assigned node optimizes the initial query plan using a cost analysis function (e.g., processing time, processing resources, etc.). Once the query plan is optimized, it is sent, via the system communication resources 14, to the parallelized data store, retrieve, and/or process sub-system 12 for processing.

Within the parallelized data store, retrieve, and/or process sub-system 12, a computing device is designated as a primary device for the query plan and receives it. The primary device processes the query plan to identify nodes within the parallelized data store, retrieve, and/or process sub-system 12 for processing the query plan. The primary device then sends appropriate portions of the query plan to the identified nodes for execution. The primary device receives responses from the identified nodes and processes them in accordance with the query plan. The primary device provides the resulting response to the assigned node of the parallelized query and response sub-system 13. The assigned node determines whether further processing is needed on the resulting response (e.g., joining, filtering, etc.). If not, the assigned node outputs the resulting response as the response to the query (e.g., a response for query no. 1 regarding data set no. 1). If, however, further processing is determined, the assigned node further processes the resulting response to produce the response to the query.

FIG. 2 is a schematic block diagram of an embodiment of the administrative sub-system 15 of FIG. 1A that includes one or more computing devices 18-1 through 18-n. Each of the computing devices executes an administrative processing function utilizing a corresponding administrative processing of administrative processing 19-1 through 19-n (which includes a plurality of administrative operations) that coordinates system level operations of the database system.

The bulk data sub-system 23 includes a plurality of computing devices 18-1 through 18-n. The computing devices of the bulk data sub-system 23 execute a bulk data processing function to retrieve a table from a network storage system 21 (e.g., a server, a cloud storage service, etc.).

The parallelized ingress sub-system 24 includes a plurality of ingress data sub-systems 25-1 through 25-p that each include a local communication resource of local communication resources 26-1 through 26-p and a plurality of computing devices 18-1 through 18-n. Each of the computing devices of the parallelized ingress sub-system 24 execute an ingress data processing function utilizing an ingress data processing of ingress data processing 28-1 through 28-n of each ingress data sub-system 25-1 through 25-p that enables the computing device to stream data of a table (e.g., a data set 30-2 as segments 29-1-1 through 29-1-n and through 29-1-p through 29-n-p) into the database system 10 of FIG. 1A via a wide area network 22 (e.g., cellular network, Internet, telephone network, etc.). The streaming may further be via corresponding local communication resources 26-1 through 26-p and via the system communication resources 14 of FIG. 1A. With the plurality of ingress data sub-systems 25-1 through 25-p, data from a plurality of tables can be streamed into the database system 10 at one time (e.g., simultaneously utilizing two or more of the ingress data sub-systems 25-1 through 25-p in a parallel fashion).

Each of the bulk data processing function and the ingress data processing function generally function as described with reference to FIG. 1 for processing a table for storage. The bulk data processing function is geared towards retrieving data of a table in a bulk fashion (e.g., a data set 30-1 as the table is stored and retrieved, via the system communication resources 14 of FIG. 1A, from storage as segments 29-1 through 29-n). The ingress data processing function, however, is geared towards receiving streaming data from one or more data sources. For example, the ingress data processing function is geared towards receiving data from a plurality of machines in a factory in a periodic or continual manner as the machines create the data.

As will be described in greater detail with reference to one or more subsequent figures, a computing device includes a plurality of nodes and each node includes a plurality of processing core resources. Each processing core resource is capable of executing at least a portion of the bulk data processing function or the ingress data processing function.

Each of the computing devices executes a query (Q) & response (R) function utilizing a corresponding Q & R processing of Q & R processing 33-1 through 33-n. The computing devices are coupled to the wide area network 22 of FIG. 4 to receive queries (e.g., query no. 1 regarding data set no. 1) regarding tables and to provide responses to the queries (e.g., response for query no. 1 regarding the data set no. 1). For example, the plurality of computing devices 18-1 through 18-n receives a query, via the wide area network 22, issues, via the system communication resources 14 of FIG. 1A, query components 31-1 through 31-n to the parallelized data store, retrieve, &/or process sub-system 12 of FIG. 1A, receives, via the system communication resources 14, results components 32-1 through 32-n, and issues, via the wide area network 22, a response to the query.

Each storage cluster includes a corresponding local communication resource of a plurality of local communication resources 26-1 through 26-z and includes a plurality of computing devices 18-1 through 18-5 and each computing device executes an input, output, and processing (IO &P) function utilizing a corresponding IO &P function of IO &P functions 34-1 through 34-5 to produce at least a portion of a resulting response. Each local communication resource may be implemented with a local communication resource of the local communication resources 26-1 through 26 p of FIG. 4 . The number of computing devices in a cluster corresponds to the number of segments in which a data partitioned is divided. For example, if a data partition is divided into five segments, a storage cluster includes five computing devices. Each computing device then stores one of the segments. As an example of operation, segments 29 are received, via the system communication resources 14 of FIG. 1A and via the local communication resources 26-1, for storage by computing device 18-4-1. Subsequent to storage, query components 31 (e.g., a query) are received, via the system communication resources 14 and the local communication resources 26-1, by the computing device 18-4-1 for processing by the IO & P data processing 34-4-1 to produce result components 32 (e.g., query response).

For example, device management of a node is supported by the computer operating system, while process management, memory management, and file system management are supported by the database overriding operating system. To override the computer OS, the database overriding OS provides instructions to the computer OS regarding which management tasks will be controlled by the database overriding OS. The database overriding OS also provides notification to the computer OS as to which sections of the main memory it is reserving exclusively for one or more database functions, operations, and/or tasks. One or more examples of the database overriding operating system are provided in subsequent figures.

In another example, the parallelized data input-subsystem divides the data set into more than two partitions. In yet another example, the parallelized data input-subsystem divides the data set into many partitions and at least two of the partitions have a different number of rows.

FIG. 17 illustrates an example of the parallelized data input-subsystem dividing a data partition into a plurality of segments to form a segment group. The number of segments in a segment group is a function of the data redundancy encoding. In this example, the data redundancy encoding is single parity encoding from four data pieces; thus, five segments are created. In another example, the data redundancy encoding is a two parity encoding from four data pieces; thus, six segments are created. In yet another example, the data redundancy encoding is single parity encoding from seven data pieces; thus, eight segments are created.

FIG. 18 illustrates an example of data for segment 1 of the segments of FIG. 17 . The segment is in a raw form since it has not yet been key column sorted. As shown, segment 1 includes 8 rows and 32 columns. The third column is selected as the key column and the other columns stored various pieces of information for a given row (i.e., a record).

As an example, the table is regarding a fleet of vehicles. Each row represents data regarding a unique vehicle. The first column stores a vehicle ID, the second column stores make and model information of the vehicle. The third column stores data as to whether the vehicle is on or off. The remaining columns store data regarding the operation of the vehicle such as mileage, gas level, oil level, maintenance information, routes taken, etc.

With the third column selected as the key column, the other columns of the segment are to be sorted based on the key column. Prior to sorted, the columns are separated to form data slabs. As such, one column is separated out to form one data slab.

FIG. 19 illustrates an example of the parallelized data input-subsystem dividing segment 1 of FIG. 18 into a plurality of data slabs. A data slab is a column of segment 1. In this figure, the data of the data slabs has not been sorted. Once the columns have been separated into data slabs, each data slab is sorted based on the key column. Note that more than one key column may be selected and used to sort the data slabs based on two or more other columns.

FIG. 20 illustrates an example of the parallelized data input-subsystem sorting the each of the data slabs based on the key column. In this example, the data slabs are sorted based on the third column which includes data of “on” or “off”. The rows of a data slab are rearranged based on the key column to produce a sorted data slab. Each segment of the segment group is divided into similar data slabs and sorted by the same key column to produce sorted data slabs.

FIG. 21 illustrates an example of each segment of the segment group sorted into sorted data slabs. The similarity of data from segment to segment is for the convenience of illustration. Note that each segment has its own data, which may or may not be similar to the data in the other sections.

FIG. 22 illustrates an example of a segment structure for a segment of the segment group. The segment structure for a segment includes the data & parity section, a manifest section, one or more index sections, and a statistics section. The segment structure represents a storage mapping of the data (e.g., data slabs and parity data) of a segment and associated data (e.g., metadata, statistics, key column(s), etc.) regarding the data of the segment. The sorted data slabs of FIG. 16 of the segment are stored in the data & parity section of the segment structure. The sorted data slabs are stored in the data & parity section in a compressed format or as raw data (i.e., non-compressed format). Note that a segment structure has a particular data size (e.g., 32 Giga-Bytes) and data is stored within in coding block sizes (e.g., 4 Kilo-Bytes).

Before the sorted data slabs are stored in the data & parity section, or concurrently with storing in the data & parity section, the sorted data slabs of a segment are redundancy encoded. The redundancy encoding may be done in a variety of ways. For example, the redundancy encoding is in accordance with RAID 5, RAID 6, or RAID 10. As another example, the redundancy encoding is a form of forward error encoding (e.g., Reed Solomon, Trellis, etc.).

The manifest section stores metadata regarding the sorted data slabs. The metadata includes one or more of, but is not limited to, descriptive metadata, structural metadata, and/or administrative metadata. Descriptive metadata includes one or more of, but is not limited to, information regarding data such as name, an abstract, keywords, author, etc. Structural metadata includes one or more of, but is not limited to, structural features of the data such as page size, page ordering, formatting, compression information, redundancy encoding information, logical addressing information, physical addressing information, physical to logical addressing information, etc. Administrative metadata includes one or more of, but is not limited to, information that aids in managing data such as file type, access privileges, rights management, preservation of the data, etc.

The key column is stored in an index section. For example, a first key column is stored in index #0. If a second key column exists, it is stored in index #1. As such, for each key column, it is stored in its own index section. Alternatively, one or more key columns are stored in a single index section.

The statistics section stores statistical information regarding the segment and/or the segment group. The statistical information includes one or more of, but is not limited, to number of rows (e.g., data values) in one or more of the sorted data slabs, average length of one or more of the sorted data slabs, average row size (e.g., average size of a data value), etc. The statistical information includes information regarding raw data slabs, raw parity data, and/or compressed data slabs and parity data.

FIG. 23 illustrates the segment structures for each segment of a segment group having five segments. Each segment includes a data & parity section, a manifest section, one or more index sections, and a statistic section. Each segment is targeted for storage in a different computing device of a storage cluster. The number of segments in the segment group corresponds to the number of computing devices in a storage cluster. In this example, there are five computing devices in a storage cluster. Other examples include more or less than five computing devices in a storage cluster.

FIG. 24 illustrates an example of redundancy encoding using single parity encoding. The data of each segment of a second group 102 is divided into data blocks (e.g., 4 K bytes). The data blocks of the segments are logically aligned such that the first data blocks of the segments are aligned. For example, coding block 1_1 (the first number represents the code block number in the segment and the second number represents the segment number, thus 1_1 is the first code block of the first segment) is aligned with the first code block of the second segment (code block 1_2), the first code block of the third segment (code block 1_3), and the first code block of the fourth segment (code block 1_4). This forms a data portion of a coding line 104.

The four data coding blocks are exclusively ORed together to form a parity coding block, which is represented by the gray shaded block 1_5. The parity coding block is placed in segment 5 as the first coding block. As such, the first coding line includes four data coding blocks and one parity coding block. Note that the parity coding block is typically only used when a data code block is lost or has been corrupted. Thus, during normal operations, the four data coding blocks are used.

To balance the reading and writing of data across the segments of a segment group, the positioning of the four data coding blocks and the one parity coding block are distributed. For example, the position of the parity coding block from coding line to coding line is changed. In the present example, the parity coding block, from coding line to coding line, follows the modulo pattern of 5, 1, 2, 3, and 4. Other distribution patterns may be used. In some instances, the distribution does not need to be equal. Note that the redundancy encoding may be done by one or more computing devices 18 of the parallelized data input sub-system 11 and/or by one or more computing devices of the parallelized data store, retrieve, &/or process sub-system 12.

FIG. 25 illustrates an overlay of the dividing of a data set 30 (e.g., a table) into data partitions 106-1 and 106-2. Each partition is then divided into one or more segment groups 102. Each segment group 102 includes a number of segments. Each segment is further divided into coding blocks, which include data coding blocks and parity coding blocks.

FIG. 26 is a schematic block diagrams of an example of storing a processed table or data set 30 in the database system 10. In this example, the parallelized data input sub-system 11 sends, via local communication resources 26-1 through 26-3, segment groups of data partitions of the data set 30 (e.g., table) to storage clusters 35-1 through 35-3 of the parallelized data store, retrieve, &/or process sub-system 12. In this example, each storage cluster includes five computing devices, as such, a segment group includes five segments.

Each storage cluster has a primary computing device 18 for receiving incoming segment groups. The primary computing device 18 is randomly selected for each ingesting of data or is selected in a predetermined manner (e.g., a round robin fashion). The primary computing device 18 of each storage cluster 35 receives the segment group and then provides the segments to the computing devices 18 in its cluster 35; including itself. Alternatively, the parallelized data input-section 11 sends, via a local communication resource 26, each segment of a segment group to a particular computing device 18 within the storage clusters 35.

FIG. 27 illustrates a storage cluster 35 distributing storage of a segment group among its computing devices and the nodes within the computing device. Within each computing device, a node is selected as a primary node for dividing a segment into segment divisions and distributing the segment divisions to the nodes; including itself. For example, node 1 of computing device (CD) 1 receives segment 1. Having x number of nodes in the computing device 1, node 1 divides the segment into x segment divisions (e.g., seg 1_1 through seg 1_x, where the first number represents the segment number of the segment group and the second number represents the division number of the segment). Having divided the segment into divisions (which may include an equal amount of data per division, an equal number of coding blocks per division, an unequal amount of data per division, and/or an unequal number of coding blocks per division), node 1 sends the segment divisions to the respective nodes of the computing device.

FIG. 28 illustrates notes 37-1 through 37-x of a computing device 18 distributing storage of a segment division among its processing core resources 48 (PCR). Within each node, a processing core resource (PCR) is selected as a primary PCR for dividing a segment division into segment sub-divisions and distributing the segment sub-divisions to the other PCRs of the node; including itself. For example, PCR 1 of node 1 of computing device 1 receives segment division 1_1. Having n number of PCRs in node 1, PCR 1 divides the segment division 1 into n segment sub-divisions (e.g., seg 1_1_1 through seg 1_1_n, where the first number represents the segment number of the segment group, the second number represents the division number of the segment, and the third number represents the sub-division number). Having divided the segment division into sub-divisions (which may include an equal amount of data per sub-division, an equal number of coding blocks per sub-division, an unequal amount of data per sub-division, and/or an unequal number of coding blocks per sub-division), PCR 1 sends the segment sub-divisions to the respective PCRs of node 1 of computing device 1.

FIG. 29 is a schematic block diagram of an example of a first computing entity 160 receiving data 162. The data 162 includes rows and columns. As an example, the rows correspond to data records and the column corresponds to fields of a data record. As a specific example, the data 162 is regarding employee records, where a row corresponds to a particular employee and the columns include employee ID, employee name, employment date, salary, home address, etc.

The first computing entity 160 includes one or more of: one or more computing devices of the parallelized data input sub-system 11 of the database system 10, one or more nodes of the one or more of the computing devices, and one or more processing core resources of the one or more nodes. The first computing entity 160 processes the data 162 for storage in a second computing entity 170 as discussed with reference to one or more of FIGS. 30-42 . The second computing entity 170 includes one or more of: one or more computing devices of the parallelized data store, retrieve, &/or process sub-system 12 of the database system 10, one or more nodes of the one or more of the computing devices, and one or more processing core resources of the one or more nodes.

While the data 162 is shown with the rows in the horizontal direction and the columns in the vertical direction, the orientation and/or data structure of the data 162 may be different. For example, the rows are orientated in the vertical direction and the columns are orientated in the horizontal direction. As another example, each record is its own data object and the data objects of the data are linked together.

FIG. 30 is a schematic block diagram of an example of the first computing entity 160 identifying a key column 164 of the data 162 on a desired sort criteria for the data. The desired sort criteria are reflective of how the data is to be sorted for a known query or for a likely query. For example, if a query is regarding an annual report of any type (e.g., sales, new hires, etc.), sorting data based on dates would be desired. As a further example, the query is further requiring the annular report to be broken down by departments; thus, it would be further desired to sort the data based on department ID.

The first computing entity 160 can identify the key column in a variety of ways. For example, the first computing entity determines the desired sorting criteria by receiving them from a requesting computing device. The first computing entity receives the desired sort criteria along with the data 162 or receives them in a separate message. In this example, the desired sorting criteria identifies the one or more key columns.

In another example, the first computing entity interprets a type of data records to identify the one or more key columns. The desired sort criteria provide interpretation rules for different types of records. For example, employee records are often sorted based on employee ID, employee department, and/or employee salary. In this example, the first computing entity would select one or more key columns to corresponds to employee ID, employee department, and/or employee salary. In another example, financial data is often sorted by data, transaction amount, purchaser ID, and/or seller ID.

While this example shows the first computing entity selecting one key column, the first computing entity could select more than one key column based on the desired sort criteria. Note that the key column is one of the columns of the data 162. Further note that, in this example, the data 162 is unsorted (i.e., it is as it was received).

FIG. 31 is a schematic block diagram of an example of the first computing entity sorting columns and the second computing entity storing an unsorted key column and the sorted columns. In the unsorted data 162, it includes columns 0-7 and rows a-1. Column 0 has been selected as the key column. Based on the data in the fields of the key column 164, the other columns are sorted to produce sorted other columns 166.

As an example, the data 162 is regarding employee information where column 0 is for department ID, column 1 is for employee first name, column 2 is for employee last name, column 3 is for date of hire, column 4 is for salary, column 5 is for tax deductions, column 6 is for insurance program, and column 7 is for other withholdings. The data 162 was created in accordance with the date of hire. Thus, record “a” is for a first employee hired, record “b” is for a second employee hired, and so on. The data 162, is to be sorted based on the column 0, which is the department ID.

The first computing entity 160 sorts the other columns 1-7 based on the department ID of column 1. Assume that there are 3 different department IDs (1, 2, and 3). Further assume that employees “c”, “g”, “I”, and “h” are in department 1; employees “a”, “d”, and “b” are in department 2, and employees “j”, “f”, “k”, “e”, and “l” are in department 3. Accordingly, the first computing entity sorts the other columns based on the key column to produce the sorted other columns 166 of “c”, “g”, “I”, “h”, “a”, “d”, “b”, “j”, “f”, “k”, “e”, and “l”.

The first computing entity 160 sends the unsorted key column 164 and the sorted other columns 166 to the second computing entity 170. The second computing entity 170 stores the unsorted key column 164 in a first storage location 172 and stores the sorted other columns 166 in a second storage location 174. In an embodiment and with reference to FIG. 22 , the first storage location 172 corresponds to one or more of the index sections of a segment data structure and the second storage location 174 corresponds to the data & parity section of the segment data structure.

FIG. 32 is a schematic block diagram of an example that is similar to the example of FIG. 31 . In this example, however, the first computing entity 160 sorts the key column 164 based on its contents as well as sorting the other columns. The first computing entity sends the sorted key column 164 and the sorted other columns 166 to the second computing entity 170. The second computing entity 170 stores the sorted key column in the first storage location 172 and the sorted other columns 166 in the second storage location 174.

FIG. 33 is a schematic block diagram of an example of the first computing device identifying a plurality of key columns of the data 162. In this example, the data includes records “a”-“1” and columns 0-7. Columns 0 and 3 are selected as the key columns 164-1. The key columns are selected in a manner as discussed with reference to FIG. 30 .

FIG. 34 is a schematic block diagram of an example of the first computing entity 160 sorting the other columns and the second computing entity 170 storing unsorted key column 164-1 and the sorted other columns 166-1. This example expands on the example of FIG. 31 where the data 162 is regarding employee information. The data includes column 0 for department ID, column 1 for employee first name, column 2 for employee last name, column 3 for date of hire, column 4 for salary, column 5 for tax deductions, column 6 for insurance program, and column 7 for other withholdings.

With columns 0 (department 1D) and column 3 (date of hire) as the key columns, the other columns are sorted by department ID and date of hire. As with the example of FIG. 31 , assume that there are 3 different department IDs (1, 2, and 3). Further assume that employees “c”, “g”, “I”, and “h” are in department 1; employees “a”, “d”, and “b” are in department 2, and employees “j”, “f”, “k”, “e”, and “l” are in department 3. Within department 1, “c” was hired before “g” who was hired before “I” who was hired before “h”. Within department 2, “a” was hired before “d” who was hired before “b”. Within department 3, “j” was hired before “f” who was hired before “k” who was hired before “e” who was hired before “l”. The resulting sort of the other columns yields the sort order of “c”, “g”, “I”, “h”, “a”, “d”, “b”, “j”, “f”, “k”, “e”, and “l”.

FIG. 35 is a schematic block diagram of an example of the first computing entity dividing data 162 into segments. In this example, the data 162 includes rows “a”-“l” and columns 0-7. The data 162 is segmented into three segments (1, 2, and 3). The first segment includes rows “a”-“d”, the second segment includes rows “e”-“h”, and the third segment includes rows “i”-“l”. The first computing entity 160 selected column 0 as the key column. Note that the data 162 may corresponds to a data partition as discussed with reference to one or more FIGS. 15-21 .

The first computing entity 160 may segment the data in a variety of ways and into any number of segments. For example, the first computing entity divides the data by a value such that each segment has that value of rows in it. As a specific example, the data includes 20 rows and the value is 5, then the first computing entity divides the data into 4 (e.g., 20/5) segments, each having 5 rows. As another example, the first computing entity has a value for the number of segments to create. As a specific example, the first computing entity is to create 3 segments from the data. When the data includes 12 rows, the first computing entity creates 3 segments, each having 4 rows. Note that, in a real-world situation, the data would include a substantial number of rows (e.g., greater than 1,000) and most likely more than eight columns.

FIG. 36 is a schematic block diagram of an example of the first computing entity 160 sorting the other columns of segments based on the key column. As a specific example, the first computing entity 160 sorts the other columns of segment 1 based on the data in column 0 of records “a”-“d” to produce sorted other columns 166 of segment 1. In particular, sorted other columns 166 of segment 1 are in the order of “b”, “d”, “a”, and “c”.

As another specific example, the first computing entity 160 sorts the other columns of segment 2 based on the data in column 0 of records “e”-“h” to produce sorted other columns 166 of segment 2. In particular, sorted other columns 166 of segment 2 are in the order of “f”, “g”, “e”, and “h”. As yet another specific example, the first computing entity 160 sorts the other columns of segment 3 based on the data in column 0 of records “i”-“l” to produce sorted other columns 166 of segment 3. In particular, sorted other columns 166 of segment 3 are in the order of “l”, “k”, “j”, and “i”.

The first computing entity 160 sends the sorted other columns of the first, second, and third segments to the second computing entity 170. The second computing entity 170 stores the first sorted segment in a first section of the second storage location 174, stores the second sorted segment in a second section of the second storage location 174, and stores the third sorted segment in a third section of the second storage location 174. As a specific example, the second computing entity includes three computing devices as shown in FIG. 37 .

The first computing entity also sends the key column of segments 1, 2, and 3 to the second computing entity. In an embodiment, the first computing entity sends the key column of the segments in an unsorted manner. In another embodiment, the first computing entity sends the key column of the segments in a sorted manner.

FIG. 37 is a schematic block diagram of an example of the second computing entity storing sorted columns and key columns of segments. In this example, the second computing entity 170 includes three computing devices 180-1 through 180-3. Each of the computing devices 180 includes its own first storage location 172-1 through 172-3 and its own second storage location 174-1 through 174-3. The first computing device 180-1 stores the key column (sorted or unsorted) of segment 1 in its first storage location 172-1 and stores the sorted other columns of segment 1 in its second storage location 174-1.

Similarly, the second computing device 180-2 stores the key column (sorted or unsorted) of segment 2 in its first storage location 172-2 and stores the sorted other columns of segment 2 in its second storage location 174-2. Also, the third computing device 180-3 stores the key column (sorted or unsorted) of segment 3 in its first storage location 172-3 and stores the sorted other columns of segment 3 in its second storage location 174-3.

FIG. 38 is a schematic block diagram of an example of the first computing entity creating parity data from sorting columns of segments. In this example, the first computing entity divides the data into a first number of segments (e.g., 3 in this example), where each segment includes its own sub-set of the records of the data. As shown, segment 1 includes rows a-d, which has the key column separate from the sorted other columns; segment 2 includes rows e-h, which has the key column separate from the sorted other columns; and segment 3 includes rows i-1, which has the key column separate from the sorted other columns. Note that there could be more than one key column, the key column may be sorted or unsorted, and the sorting of the other columns is done as previously discussed.

The first computing entity creates a fourth segment for this example that includes parity data. The first row (“m”) of the fourth segment includes the parity data created from the first rows of the other segments. For example, field m,0 includes the parity data created from the data in fields (a,0), (e,0) and (i,0). As a specific example, the data of (a,0), (e,0) and (i,0) is exclusively ORed together to produce parity data of P0(a-e-i). Parity data for the other rows are created in a similar manner.

FIG. 39 is a schematic block diagram that continues the example of FIG. 38 . In this figure, the first computing entity reorganizes the sorted columns and the key column with the parity data to produce four sorted data-parity segments. As a specific example, row “m” of the parity segment of FIG. 38 is moved to the first row of segment 1 and row “b” of segment 1 of FIG. 38 is moved to the first row of segment 4. The first sorted data-parity segment is sent to a first computing device 180-1 of the second computing entity 170 for storage. The first computing device 180-1 stores the key column of data-parity segment 1 in its first storage location 172 and stores the sorted other columns of data-arity segment 1 in its second storage location 174.

As another specific example, row “n” of the parity segment of FIG. 38 is moved to the second row of segment 2 and row “g” of segment 2 of FIG. 38 is moved to the second row of segment 4. The second sorted data-parity segment is sent to a second computing device 180-2 of the second computing entity 170 for storage. The second computing device 180-2 stores the key column of data-parity segment 2 in its first storage location 172 and stores the sorted other columns of data-parity segment 2 in its second storage location 174.

As a further specific example, row “o” of the parity segment of FIG. 38 is moved to the third row of segment 3 and row “j” of segment 3 of FIG. 38 is moved to the third row of segment 4. The third sorted data-parity segment is sent to a third computing device 180-3 of the second computing entity 170 for storage. The third computing device 180-3 stores the key column of data-parity segment 3 in its first storage location 172 and stores the sorted other columns of data-parity segment 3 in its second storage location 174.

In addition, the fourth sorted data-parity segment is sent to a fourth computing device 180-4 of the second computing entity 170 for storage. The fourth computing device 180-4 stores the key column of data-parity segment 4 in its first storage location 172 and stores the sorted other columns of data-parity segment 4 in its second storage location 174.

While FIGS. 38 and 39 show the generation of parity data and reorganization of the data as separates steps, they may be done concurrently as one step. For example, the first computing entity separates the data into four segments. Some of the rows of each segment is filled with sorted data and at least one other row is filled with parity data.

FIG. 40 is a schematic block diagram of an example of the first computing entity mapping a column of data to data blocks. The data blocks correspond to addressable logical data blocks of the memory of the second computing entity. In an example, the data block 190 is of a fixed size (e.g., 4 KB to 32 KB or more). The data content of each field can be of a varying size; sometimes less than the fixed size of a data block and sometimes more. In addition, the data content size from column to column of data 162 will likely vary as well.

In this example, the size of the data content in the fields of column 1 of the data 162 is greater than the size of a data block. As such, the data content of a field maps to multiple data blocks. As a specific example, data content 1b1 of segment 1, row b, and column 1 is mapped to three data blocks (0,0; 0,1; and 0,2), where the first number is the data block row and the second number is the data block column. As such, a first portion 1b1-00 is mapped to data block 0,0; a second portion 1b1-01 is mapped to a second data block 01; and a third portion 1b1-02 is mapped to a third data block 02. Note that the data content of a field may not fully fill each of the mapped blocks. Further note that the data blocks may be organized in a variety of ways. For example, the data blocks are organized in one column with a plurality of rows.

The other columns of the data would be mapped to data blocks in a similar manner. Thus, the segments include data content mapped to data blocks. This facilitates reading, writing, and/or processing of segments.

FIG. 41 is a schematic block diagram of an example of the first computing entity creating parity data from sorting data of a column of multiple segments. This example corresponds to column 1 of the data 162 that has been sorted and mapped to data blocks. Segment 1 column 1 includes the sorted data content for the corresponding fields (e.g., 1b1, 1d1, 1a1, and 1c1) mapped to 12 data blocks (0,0; 0,1; 0,2; 1,0; 1,1; 1,2; 2,0; 2,1; 2,2; 3,0;3,1; and 3,2). Segment 2 column 1 includes the sorted data content for the corresponding fields (e.g., 2f1, 2g1, 2e1, and 2h1) mapped to 12 data blocks (4,0; 4,1; 4,2; 5,0; 5,1; 5,2; 6,0; 6,1; 6,2; 7,0;7,1; and 7,2). Segment 3 column 1 includes the sorted data content for the corresponding fields (e.g., 3l1, 3k1, 3j1, and 3i1) mapped to 12 data blocks (8,0; 8,1; 8,2; 9,0; 9,1; 9,2; 10,0; 10,1; 10,2; 11,0;11,1; and 11,2).

The first computing entity also creates a fourth segment for parity data that is created from the data content of the data blocks. For example, data content 1b1-00, 2f1-00, and 3i1-00 are exclusive ORed together to produce parity data P00 (b-f-1). As another example, data content 1b1-01, 2f1-01, and 3i1-01 are exclusive ORed together to produce parity data P01 (b-f-1), and so on.

FIG. 42 is a schematic block diagram of an example of the first computing entity reorganizing sorted data blocks and the parity data of FIG. 41 . As with the example of FIG. 39 , a row of the parity data segment is exchange with a row from each of the other segments. While FIGS. 41 and 42 show the generation of parity data for data blocks and reorganization of the data blocks as separates steps, they may be done concurrently as one step.

FIG. 43 is a schematic block diagram of an example of a computing device 18 having an application specific operating system 51 and a computing device operating system (CD OS) for its non-volatile (NV) memories (1-aa) (e.g., e.g., each NV memory includes one or more NV memory devices coupled to a NV memory interface module that includes a driver) and the main volatile memory 40. In this example, the main volatile memory 40 is divided into two sections: a first section 140 that is dedicated for use in conjunction with the computing device operating system and a second section 142 that is dedicated for use in conjunction with the application specific operating system 51.

In this example, NV memory 1 and the dedicated CD memory 140 are operable in accordance with the CS OS file system management operation 134, the CD OS device management operation 138, and CD OS memory management operation 132 of the computing device OS. The remaining NV memories 2-aa are selectively operable in accordance with the CS OS or in accordance with the application specific operating system 51.

For instance, NV memory 2 is operable, for file system management, device management, and/or memory management, in accordance with the CS OS or the application specific OS 51. In particular, a custom file system 124-2, a device 120, and/or memory 126-2 management instruction sets for NV memory 2 generate an enable/disable signal to select which file system, device management, and/or memory management to use. For example, when the signal is enabled and via the multiplexer (which is a logical function), NV memory 2 and a portion of memory section 142 operate in accordance with the custom file system 124-2, device 120-2, and/or memory 126-2 management instruction set(s) of the application specific OS 51. When the signal is disabled, NV memory 2 operates in accordance with the CD OS file system 134, device 138, and/or memory 136 management instruction sets.

Each of the remaining NV memories (3-aa) have similar selectability as to which file system management instruction set to use, which device management instruction set to use, and/or which memory management instruction set to use. In this embodiment, each NV memory has its own custom file system, device, and/or memory management instruction set(s) 124-2 through 124-aa, 120-2 through 120-aa, and/or 126-2 through 126-cc.

FIG. 44 is a schematic block diagram that is similar to FIG. 43 with the difference being that this figure includes a common custom file system, device, and/or memory management instruction sets 124, 120, and/or 126 of the application specific operating system 51. For example, the file system management instruction set 124 is common for NV memories 2-aa; yet, for each NV memory, the particular file system management instruction set to use (e.g., 124 or 134) is individually selectable. As another example, the memory management instruction set 126 is common for NV memories 2-aa; yet, for each NV memory, the particular memory management instruction set to use (e.g., 126 or 136) is individually selectable. As a further example, the device management instruction set 120 is common for NV memories 2-aa; yet, for each NV memory, the particular device management instruction set to use (e.g., 120 or 130) is individually selectable.

FIG. 45 is a logic diagram of an example of processing a table or data set into raw (e.g., unsorted by a key column) data segments. In particular, a method is presented for use with one or more functions and features described in conjunction with FIGS. 1-44 . The method includes step 450, where a processing core resource, a node, a computing device, or devices, (hereinafter for this figure referred to as a computing node) of the parallelized data input sub-system receives a data set (e.g., a table).

The method further includes step 452, where the computing node determines whether to partition the data set. The determining whether to partition the data set includes one or more of a size of the data and a determination of how the data set may be subsequently analyzed (e.g., partitioned by time of day, predicted query for the data set, etc.). In an example, the analyzation determination is based on or more of a data tag (e.g., data file identifier, data type identifier (e.g., audio, picture, text, etc.)) associated with the data set, a size of the data set, a type of the data set, and a command.

When determining to partition the data set, the method includes step 454, where the computing node ascertains partitioning parameters (e.g., one or more of segment size, number of computing devices in a cluster, number of nodes, number of processing core resources, data block size, memory formatting, network formatting, query processing information (how the data will need to be sorted, retrieved, and/or processed for queries), etc.). The method includes step 456, where the computing node partitions the data set into a plurality of data partitions in accordance with the partitioning parameters.

When determining to not partition the data set, the method includes step 458, where the computing node treats the data set as one data partition. The method further includes step 460, where the computing node determines a coding scheme for the partition(s). In an example, the coding scheme is based on a number of computing devices available in a storage cluster. For example, when ten computing devices are available, the computing node determines a coding scheme of 10 or less parity and data segments (e.g., 7 data & 3 parity, 6 data & 4 parity, 6 data & 3 parity, etc.). The method further includes step 462, where the computing node determines a number of segments in a segment group for each data partition. For example, the number of segments is based on a coding scheme for encoding the data set before storage. As a specific example, when the coding scheme is parity encoding of four data pieces to produce one parity piece, then five pieces are created (e.g., four for the data pieces and one for the parity piece) and the number of segments in a group is five.

The method further includes step 464, where the computing node determines a number of segments in a segment group to be created for each data partition based on one or more of a variety of factors. The factors include, but are not limited to, data block size, number of processing core resources available, number of nodes available, number of computing devices available, number of storage clusters, etc. Note a segment group corresponds to data and parity segments regarding a data partition. The method further includes step 466, where the computing node divides a data partition into raw segments for each segment group.

FIG. 46 is a logic diagram of an example of processing a raw data segment of a table or data set for storage in the database system. In particular, a method is presented for use with one or more functions and features described in conjunction with FIGS. 1-46 . The method includes step 470, where a processing core resource, a node, a computing device, or devices, (hereinafter for this figure referred to as a computing node) of the parallelized data input sub-system receives a data set (e.g., a table). The method further includes step 472, where the computing node organizes the raw (e.g., unsorted, uncompressed, and/or unprocessed) data segment into a plurality of data slabs. For example, a data slab corresponds to a column of a table.

The method further includes step 474, where the computing node sorts a data slab in accordance with one or more key columns (i.e., one or more selected columns of the table used to sort the data slab). The method further includes step 476, where the computing node organizes the sorted data slabs, less the key column(s), to produce a plurality of sorted data slabs (i.e., a sorted data segment).

The method further includes step 478, where the computing node performs a redundancy function (e.g., parity, RAID 5, RAID 6, RAID 10, erasure encoding, etc.) on the sorted data segment to produce parity data. The method further includes step 480, where the computing node intersperses the parity data with the sorted data to produce data & parity of a data & parity section of a segment. The method further includes step 482, where the computing node stores the key column(s) in a manifest and/or an index section of the segment. The manifest section stores metadata of the data and/or parity of the data & parity section of the segment.

The method further includes step 482, where the computing node creates a statistics sections for the segment for storing statistical information regarding the segment. For example, the statistics section stores number of rows in a table, number of rows in a data slab, average length of a variable length column, average row length, etc. The method further includes step 486, where the computing node sends the segment of a segment group to a computing device of a specific storage cluster.

FIG. 47 is a logic diagram of an example of partitioning and segmenting a table or data set for storage in the database system. In particular, a method is presented for use with one or more functions and features described in conjunction with FIGS. 1-46 .

The method includes step 500, where a processing core resource, a node, a computing device, or devices, (hereinafter for this figure referred to as a computing node) of the parallelized data input sub-system determines a storage coding scheme (e.g., 4 of 5 single parity). The method further includes step 502, where the computing node determines a partitioning scheme. For example, the computing node determines the partitioning scheme includes partitioning the data set into AM and PM times. The method further includes step 504, where the computing node determines a number of segments per partition based on the coding scheme. For example, when the storage coding scheme is 4 of 5 single parity, the computing node determines the number of segments is 5.

The method further includes step 506, where the computing node determines a size of each segment (e.g., 32 Gigabytes (GB)). In an example, the size is fixed for a system. In another example, the size varies from storage cluster to storage cluster. For example, a first storage cluster stores segments of 1 Terabyte (TB) and a second storage cluster stores segments of 32 GBs. The method further includes step 508, where the computing node determines a number of rows per segment based on row size and segment size. For example, when a row is 16 KB and the segment is 32 GB, the computing node determines there are two million rows per segment. Note a full row has to exist within a segment.

The method further includes step 510, where the computing node determines a number of segment groups per partition based on one or more of the segment size and a partition size (e.g., variable based on size of data and multiple of segment size).

It is noted that terminologies as may be used herein such as bit stream, stream, signal sequence, etc. (or their equivalents) have been used interchangeably to describe digital information whose content corresponds to any of a number of desired types (e.g., data, video, speech, text, graphics, audio, etc. any of which may generally be referred to as ‘data’).

As may be used herein, the terms “substantially” and “approximately” provides an industry-accepted tolerance for its corresponding term and/or relativity between items. For some industries, an industry-accepted tolerance is less than one percent and, for other industries, the industry-accepted tolerance is 10 percent or more. Other examples of industry-accepted tolerance range from less than one percent to fifty percent. Industry-accepted tolerances correspond to, but are not limited to, component values, integrated circuit process variations, temperature variations, rise and fall times, thermal noise, dimensions, signaling errors, dropped packets, temperatures, pressures, material compositions, and/or performance metrics. Within an industry, tolerance variances of accepted tolerances may be more or less than a percentage level (e.g., dimension tolerance of less than +/−1%). Some relativity between items may range from a difference of less than a percentage level to a few percent. Other relativity between items may range from a difference of a few percent to magnitude of differences.

As may also be used herein, the term(s) “configured to”, “operably coupled to”, “coupled to”, and/or “coupling” includes direct coupling between items and/or indirect coupling between items via an intervening item (e.g., an item includes, but is not limited to, a component, an element, a circuit, and/or a module) where, for an example of indirect coupling, the intervening item does not modify the information of a signal but may adjust its current level, voltage level, and/or power level. As may further be used herein, inferred coupling (i.e., where one element is coupled to another element by inference) includes direct and indirect coupling between two items in the same manner as “coupled to”.

As may even further be used herein, the term “configured to”, “operable to”, “coupled to”, or “operably coupled to” indicates that an item includes one or more of power connections, input(s), output(s), etc., to perform, when activated, one or more its corresponding functions and may further include inferred coupling to one or more other items. As may still further be used herein, the term “associated with”, includes direct and/or indirect coupling of separate items and/or one item being embedded within another item.

As may be used herein, the term “compares favorably”, indicates that a comparison between two or more items, signals, etc., provides a desired relationship. For example, when the desired relationship is that signal 1 has a greater magnitude than signal 2, a favorable comparison may be achieved when the magnitude of signal 1 is greater than that of signal 2 or when the magnitude of signal 2 is less than that of signal 1. As may be used herein, the term “compares unfavorably”, indicates that a comparison between two or more items, signals, etc., fails to provide the desired relationship.

As may be used herein, one or more claims may include, in a specific form of this generic form, the phrase “at least one of a, b, and c” or of this generic form “at least one of a, b, or c”, with more or less elements than “a”, “b”, and “c”. In either phrasing, the phrases are to be interpreted identically. In particular, “at least one of a, b, and c” is equivalent to “at least one of a, b, or c” and shall mean a, b, and/or c. As an example, it means: “a” only, “b” only, “c” only, “a” and “b”, “a” and “c”, “b” and “c”, and/or “a”, “b”, and “c”.

One or more embodiments have been described above with the aid of method steps illustrating the performance of specified functions and relationships thereof. The boundaries and sequence of these functional building blocks and method steps have been arbitrarily defined herein for convenience of description. Alternate boundaries and sequences can be defined so long as the specified functions and relationships are appropriately performed. Any such alternate boundaries or sequences are thus within the scope and spirit of the claims. Further, the boundaries of these functional building blocks have been arbitrarily defined for convenience of description. Alternate boundaries could be defined as long as the certain significant functions are appropriately performed. Similarly, flow diagram blocks may also have been arbitrarily defined herein to illustrate certain significant functionality.

To the extent used, the flow diagram block boundaries and sequence could have been defined otherwise and still perform the certain significant functionality. Such alternate definitions of both functional building blocks and flow diagram blocks and sequences are thus within the scope and spirit of the claims.

One or more functions associated with the methods and/or processes described herein can be implemented via a processing module that operates via the non-human “artificial” intelligence (AI) of a machine. Examples of such AI include machines that operate via anomaly detection techniques, decision trees, association rules, expert systems and other knowledge-based systems, computer vision models, artificial neural networks, convolutional neural networks, support vector machines (SVMs), Bayesian networks, genetic algorithms, feature learning, sparse dictionary learning, preference learning, deep learning and other machine learning techniques that are trained using training data via unsupervised, semi-supervised, supervised and/or reinforcement learning, and/or other AI. The human mind is not equipped to perform such AI techniques, not only due to the complexity of these techniques, but also due to the fact that artificial intelligence, by its very definition—requires “artificial” intelligence—i.e. machine/non-human intelligence.

One or more functions associated with the methods and/or processes described herein can be implemented as a large-scale system that is operable to receive, transmit and/or process data on a large-scale. As used herein, a large-scale refers to a large number of data, such as one or more kilobytes, megabytes, gigabytes, terabytes or more of data that are received, transmitted and/or processed. Such receiving, transmitting and/or processing of data cannot practically be performed by the human mind on a large-scale within a reasonable period of time, such as within a second, a millisecond, microsecond, a real-time basis or other high speed required by the machines that generate the data, receive the data, convey the data, store the data and/or use the data.

One or more functions associated with the methods and/or processes described herein can require data to be manipulated in different ways within overlapping time spans. The human mind is not equipped to perform such different data manipulations independently, contemporaneously, in parallel, and/or on a coordinated basis within a reasonable period of time, such as within a second, a millisecond, microsecond, a real-time basis or other high speed required by the machines that generate the data, receive the data, convey the data, store the data and/or use the data.

One or more functions associated with the methods and/or processes described herein can be implemented in a system that is operable to electronically receive digital data via a wired or wireless communication network and/or to electronically transmit digital data via a wired or wireless communication network. Such receiving and transmitting cannot practically be performed by the human mind because the human mind is not equipped to electronically transmit or receive digital data, let alone to transmit and receive digital data via a wired or wireless communication network.

One or more functions associated with the methods and/or processes described herein can be implemented in a system that is operable to electronically store digital data in a memory device. Such storage cannot practically be performed by the human mind because the human mind is not equipped to electronically store digital data.

One or more functions associated with the methods and/or processes described herein may operate to cause an action by a processing module directly in response to a triggering event—without any intervening human interaction between the triggering event and the action. Any such actions may be identified as being performed “automatically”, “automatically based on” and/or “automatically in response to” such a triggering event. Furthermore, any such actions identified in such a fashion specifically preclude the operation of human activity with respect to these actions—even if the triggering event itself may be causally connected to a human activity of some kind.

Unless specifically stated to the contra, signals to, from, and/or between elements in a figure of any of the figures presented herein may be analog or digital, continuous time or discrete time, and single-ended or differential. For instance, if a signal path is shown as a single-ended path, it also represents a differential signal path. Similarly, if a signal path is shown as a differential path, it also represents a single-ended signal path. While one or more particular architectures are described herein, other architectures can likewise be implemented that use one or more data buses not expressly shown, direct connectivity between elements, and/or indirect coupling between other elements as recognized by one of average skill in the art.

The term “module” is used in the description of one or more of the embodiments. A module implements one or more functions via a device such as a processor or other processing device or other hardware that may include or operate in association with a memory that stores operational instructions. A module may operate independently and/or in conjunction with software and/or firmware. As also used herein, a module may contain one or more sub-modules, each of which may be one or more modules.

As may further be used herein, a computer readable memory includes one or more memory elements. A memory element may be a separate memory device, multiple memory devices, or a set of memory locations within a memory device. Such a memory device may be a read-only memory, random access memory, volatile memory, non-volatile memory, static memory, dynamic memory, flash memory, cache memory, a quantum register or other quantum memory and/or any other device that stores data in a non-transitory manner. Furthermore, the memory device may be in a form of a solid-state memory, a hard drive memory or other disk storage, cloud memory, thumb drive, server memory, computing device memory, and/or other non-transitory medium for storing data. The storage of data includes temporary storage (i.e., data is lost when power is removed from the memory element) and/or persistent storage (i.e., data is retained when power is removed from the memory element). As used herein, a transitory medium shall mean one or more of: (a) a wired or wireless medium for the transportation of data as a signal from one computing device to another computing device for temporary storage or persistent storage; (b) a wired or wireless medium for the transportation of data as a signal within a computing device from one element of the computing device to another element of the computing device for temporary storage or persistent storage; (c) a wired or wireless medium for the transportation of data as a signal from one computing device to another computing device for processing the data by the other computing device; and (d) a wired or wireless medium for the transportation of data as a signal within a computing device from one element of the computing device to another element of the computing device for processing the data by the other element of the computing device. As may be used herein, a non-transitory computer readable memory is substantially equivalent to a computer readable memory. A non-transitory computer readable memory can also be referred to as a non-transitory computer readable storage medium.

While particular combinations of various functions and features of the one or more embodiments have been expressly described herein, other combinations of these features and functions are likewise possible. The present disclosure is not limited by the particular examples disclosed herein and expressly incorporates these other combinations.
